Asolid insulating sphere of radius r = 1.0 m that carries a positive charge q1 = 1.0 mc uniformly distributed over it is concentric with a very thin insulating shell of radius 2r that carries the charge q2 = -1.0 mc. the charge q2 is distributed uniformly over the shell.
use gauss's law to obtain the magnitude of the electric field:
a. e1 inside the sphere, r < r
b. e2 between the sphere and the shell, r < r < 2r
c. e3 outside the shell, r > 2r
d. plot the electric field in the radial direction on a graph. be sure to label the actual magnitude of the electric field at r = 0, r= r, and r = 2r.
